It is now simple to read data into MATLAB without having to export and import CSVs. Nexus MATLAB integration allows MATLAB to access the open trial and import any of the data directly – trajectory, device, metadata or...
When using pipelines for processing gait data, the standard plug in gait pipeline is a great place to start but it is important to consider your specific application, system and processing requirements. This article will suggest some ways you may...
While it's important to backup data when using motion capture it is also important to create backups of configurations. The configurations include systems, pipelines, toolbars, monitors and more.
Some examples of when having backups easily...
It can be helpful to create one or even a range of custom pipelines to improve your processing workflow.
For example, if you are working with large amounts of data you may find it easier to use custom pipelines specifically for batch...
